11) (1/1 wheat [1, may roncn'n:

tie it known that l, T'nowvs l). DIHSCOLL, a citizen ot' the United States, residing at St. Louis, State of Missouri, ltave invented new amt uscl'ul Improvements in ltailway- Ties. of which the Following is a speciticatlt)ll.

This invention relates to improvements in railway ties, and the object of the invention is to provide a simple and etl'eetive tie com prising a metallic casing having its central portion material, such as cement, and its ends adjacent the said plastic material adapted For.

the reception of cushion blocks, whereby a strong and etlective tie provit'led and a certain amottnt ot resiliency atlordet t by the cushion members upon which the rails are secured.

\Vith the above and other objec s in view, which will be more apparent as the nature of the description progresses, the invention resides in tlte novel construction of ties hereinat'ter 't'ully described and claimed.

iln the accompanying drawings, Figure l is a top plan view of a tie constructed in accordance with the present intention. Fig. 9 is a side elevation of the same. Fig. 3 is a detail plan view ol the saute. Fig. t is a central longitudinal sectional view ot the same. Fig. is a detail perspective view ot one of the blocks. Fig/t; is a sectional view upon the line t3-----t3 ol' t ig. t. Fig. 7 is a similar view upon the line T--7 of Fig. 1. Fig. S is a side elevation ol' one of the plate securing and cushion sustaining meml)t The improved tie, as designated in the drawings. contemplates the employment ot a pair of substantially rectangular shells constructed o'l' metal amt t ttfiltllltltttt by the numerals l amt 2. These shells ltave their side walls. adjacent their ends. tortucd with a plurality of openings :3, and each ot the said plates has its eentrat body portion formed with an elongated opening -l. The top or lace of each of the shctls. adjacent their out away portions, are provided with a plurality of spike openings .3. the spike openings on the ttpper portion of the shell being tour in mtmber amt each pair being spaced away l'rom each other tor the reception ol' reseeuring elements, while the lower shell 2 is preferably provided with only a single pair of spaced openings.

The numeral (3 designates the cushion adapted for the reception of plastic l parent to those such Inventions "attented Aug. 22, 1911.

blocks for the ends of the tie. 'lhese cushion blocks are preferably constructed of wood and have their opposite sides or faces :tormmt with dove tailed recesses T amt S.

The lltllllt tits 9 designate theshett and cushion securing members. Each of these members is formed with a beveled head it) and a threaded extension ,1 t. The threaded extension is adapted to extend through the opening 3 and the sides of the shells 1 amt J and the said projecting portion are adapt ed to engage the registering openings provided in the side eonnecting plate .12. The projecting ends of the members 9 are socured to the side plates through the medium ot removable nuts [3. The headed portions of the members J are adapted to be snugly within the dove taitcd recesses T and S ot the cushion t' In assen'ibling the parts of the tie, the members 9 are first inserted within the open lugs 3 of the lower shell 1?. The headtd portions of the members 9 engage with the lower dove tailed recesses R of the cushion blocks (3. Spikes are tltcn inserted through the openings upon the lower face ot the shell 2 to engage with the cushions. The secur ing members 2) are next placed within the openings 3 of the up )er hett t and the said shell slid upon the lower shell causing the headed portions ot the members t to engage within the (love tailed recesses T of the block tt. The plates are then applied to the pu jet-ting portions ot the members 9 amt cured thereto through the medium of the nuts. as hcretolore stated. The tie is placed in proper position upon the road bed atut the upper portion thcreot' is adapted to ret-eive a body ot' plastic nnttct'iat such as cottcrete ll. The rails 1.3 are positioned upon the tie. amt spikes to are inserted within the openings 5 ol' the upper shell .1 to seenrely retain the rails in position upon the tie.

From the above description, taken itt connection with the acctuntnurving drawings, the advantages of the construction abovt described. as well as its eheapncss. simplicity and endurance will. it is thought, be apskitled in the art to which appertain, it being readily noted that the cu hion blocks may he removed and supplanted with additional blocks when tht original cushions become worn or damag d, that the concrete body adds nntterially to the lit'eof the tie and itv is to be further understood that while I have illustrated and described the preferred embodiment of the improvement as i'tnow appears teme, minor changes of construction within the scope of the appended claims may he made, if desired.

Having thus fully described the said inj Vention, What I claim is:

A tie for railway rails comprisinga pair 'of rectangular shells, each of said shells being of a substantially U-shapecl form, the. faces or connecting members or the U-shapetl shells heingeach centrally formed with rec tangular openings, the sidewalls of each of the shells being formed with a plurality of perforations, the faces of the shells being each provided With spike receivingopenings, the central open portion oi the shell atlaptl eel tor the reeeption ot a plastic hotly, cushion blocks for the emls of the shells, hevelecl lieacletl securing members adapted to proect'through the perforations 1n the sales ot the shells, each of the cush on blocks having their Sl(lCS 'fOlIllOtl with (love tailed recesses adapted to engage with the heads of the securing elements, plates having spaced perforations fltltlplQtl to engage the PlOjQC'ling portions of the securing elements, and

nuts for the said securing members amt plates.

In testimony whereof I atlix my signature.

in presence of two witnesses.
